Abstract
Reduction of intraocular pressure (IOP) is the only evidence-based treatment against glaucoma. The major methods of IOP reduction are eye drops and surgical treatments. Selective Laser Trabeculoplasty (SLT) is besed on selective photohermolysis theory. SLT is without tissue impairment, and is capable of re-treatment. SLT uses Q-switched frequency-doubled Nd:YAG laser, and it needs a few minutes for the treatment. Response rate is about 70%. IOP reduction rate is 20-30%. The IOP lowering effect of SLT is as much as that of the most effetive eye drop, and the effect lasts for a long time. And then, some group has investigated the efficacy and safety of SLT as primary treatment. SLT is expected to become a common treatment of glaucoma.
